EYE-GUARD.

Specification of Letters Patent.

Patented June 2, 1914.

Application filed October 22, 1910. Serial No. 588,561.

To all whom it may concern Be it known that I, HANS II. HANSEN, acitizen of the United States, residing at Chi cago, Cook county,Illinois, have invented certain new and useful Improvements inEye-Guards, of which the following, taken in connection with thedrawing, is a description.

My invention has for its object the production of an eye guard designedto be used by persons exposed to the wind, dust, and other conditions ofthe elements making protection for the eyes and face necessary.

My invention is particularly desirable for use by engineers and those inlike positions where a sudden change from the cold temperature outsideto the warm temperature inside of an engine cab will cause a vapor toform almost instantly on the lenses of the eye guards, thus temporarilyobscuring the vision. This objection I am able to overcome by theconstruction hereinafter set forth, and which, together with otherimprove-- ments and advantages will be more fully and in detailexplained.

In the accompanying drawings forming part of this specification I haveillustrated the principle of my invention in what I now consider thepreferred form of construction, and. in these drawings Figure 1 is afront elevation of an eye guard embodying my invention; Fig. 2 is across section taken on line 22 of Fig. 1 looking in the direction of thearrows; Fig. 3 is a front elevation of one half an eye guard with aportion of the lens and lens holding frame brokenaway to show the frameand attachment secured thereto in section; Fig. 4 is a modified form ofconstruction. Figs. 5 and 6 are respectively a plan view and sideelevation of another form of construction.

In Fig. 1 of the drawing A represents a frame of material which shall besufliciently flexible to conform to the features of the face, such forinstance as leather, which has a binding a around the outer edgesthereof. In this instance the frame A is made to fit over the eyes only,but as is obvious it may be made large enough to cover the whole face ifdesired. The eye guard is held in position by an elastic band a whichextends around the head of the wearer. The frame A is provided with theusual apertures A through which the lens holding frames B are extended,and which are preferably ale though not necessarily held in position byfrictional engagement. The lens holding frames B are preferablyconstructed of rings of metal of any kind suitable for the pur pose,which may be either round or oval, and which are provided with acircumferential groove 1) for engaging and holding in place the lensesb, I). In the periphery of the lens holding frame B is a sight openingC, which is preferably arranged to open toward the center of the eyeshield, but may be arranged at any other point in the line of vision. Amovable cover C having an elongated opening c therein is pivotallysecured at c to the outside of the periphery of the lens holding frame.One end of this cover 0 is bent at right angles to the cover to form alip or projection, by means of which the cover may be moved to open orclose the opening C.

In Fig. 4 I have shown a modified form of construction in which a roundlens is used and the lens holding frame is round. In this constructionan aperture d is provided in the lens holding frame. D is a cover havingan aperture d therein. A lip or projection d is provided by means ofwhich the cover may be moved so that the aperture cl registers with theaperture cl to open the same, or may be moved to the position shown inthe drawing when the aperture in the lens holding frame will be closed.A cord or wire (i or other securing means engages each end of the coverD and extends around the lens holding frame D as shown in Fig. 4. Thisholds the cover or shield D securely in position and allows it to beeasily and readily moved in either direction.

Persons who wear eye guards are often inconvenienced by vapor whichimmediately forms upon the lenses as the wearer changes from oneatmosphere to another, this vapor being suilicient at times to entirelyobstruct the vision. Especially to engineers is this a seriousdifficulty, but by the use of the eye guards herein described the wearersimply moves the cover over the aperture G and directs his line ofvision through the opening.

In the construction of these eye guards I prefer to make the opening inthe lens holding frame over the right eye, but it is obvious that it mayif desired he made in both frames. In each of the frames shown I haveprovided movable covers, but these covers may if desired be dispensedwith entirely if the wearer be not exposed to dust, etc., the

purpose being to provide a guard havinga lens frame projecting away fromthe face, which frame is provided with ingto be used in emergency.

In the form of construction shown in Figs. 5 and 6 I employ a round lensholding frame i E which is provided with an opening E and between saidopening and the upwardly extending flange e at the bottom of the frameis acircumferential groove 6, A cover E shapedtoconform to the peripheryof the lens holding frame closes the openingEf when it isnot desired touse the same, and

. 1. An eye guard having a flexible frame,

lensholding rings in said flexible frame which extend atrightanglesthereto, and are held in place by frictional .oengagement in said frame,each of said rings having a sina sight open- I gle observation openingin the peripheral face thereof, and an adjustable cover for closing saidopening, scribed. V

2; An eye guard having, a circular eye piece provided in a side with anobservation opening and having an annular groove forming a seat, a coverfor said observation opening, and a ring .fitted ln' sa d seat andconnected w ththe cover,

4. An eye guard having a circular eye piece formed 1n a slde with anobservation open1ng, ;a cover for saidopening, and a 50 rlng encirclingsaid eyepiece and connected substantially as dewith the cover andprovided with a p'rojecting portion forming a finger piece.

In testimony whereof I have slgnedthis Specification infthe presence oftwo subscribing witnesses. I r HANS H. 'I-IANSEN. Witnesses A. V.Wnnnoiv,
